Airtac MID Series Double Rod Mini Cylinder MID25X160S
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID25X160S is a genuine double acting, double rod round-body mini air cylinder with a Ø25mm bore and 160mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MID Series Double Rod Mini Cylinder MID25X160S
Delivering 206.1 N of thrust at 0.5 MPa in both directions, this double-acting round-body mini cylinder uses a through-rod design so extend and retract forces are perfectly equal. The twin rod resists rotation and side load, steadying guiding tasks without an external guide, while the back rod end is free to trip a switch or carry a stop. Its stainless-steel barrel and rod shrug off mild corrosion and washdown environments.
Built to the ISO 6432 mounting interface, the 25 mm bore drops into standard mini brackets and clevises. It moves a vertical load of about 10.5 kg each way with a 2:1 safety margin, and the -S suffix means a piston magnet is fitted for CMSG, DMSG or EMSG switches. Air connects via 1/8" ports, and fixed TPU bumper pads decelerate the stroke ends.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X160S Is Used
Symmetric Shuttle Transfer
Moves lightweight trays between two stations using the equal 206.1 N force both ways, with the twin rod preventing twist during the rapid 160 mm traverse.
Back-Rod Switch Trip
Uses the protruding rear rod end to physically trigger an external limit flag, while the internal -S magnet simultaneously fires a DMSG sensor for dual confirmation.
Guided Push Operation
Pushes a 10 kg fixture forward and back without needing an external guide rail, relying on the 10 mm twin rod to resist side load and rotation.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X160S the Right Cylinder?
If 206.1 N at 0.5 MPa is too much, step down to the MID20 bore which provides 131.9 N; if you need more push, the MID32 offers 345.6 N. This 160 mm stroke sits well within the 500 mm maximum standard stroke for this bore. Choose this double-rod variant when you need anti-rotation stability, a back-rod stop, or symmetric shuttle movements.
Mount using LB foot, FA flange or TC trunnion brackets (the SDB pivot block is not available on double-rod models). Because the -S magnet is present, you can fit CMSG, DMSG or EMSG sensors. Remember the fixed TPU bumpers only soften the stroke end and do not lock the piston; if air pressure drops, the cylinder drifts, so fit an external rod lock or pilot check valve to hold a suspended load.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MID Series Double Rod Mini Cylinder MID25X160S FAQ
Because a rod exits both ends, force is equal both ways: 206.1 N at 0.5 MPa, 288.5 N at 0.7 MPa, and a maximum theoretical output of 42.0 kgf at 1.0 MPa. It uses 1/8" ports and runs at 30-800 mm/s.
The through-rod resists rotation and side load, and the rear rod end can drive a second load or trip a switch. The -S magnet allows CMSG/DMSG/EMSG sensors, but note the cylinder drifts on air loss—fixed bumpers only soften the stroke end, so use a rod lock for holding.
